This report investigates how the company Vätternkök AB can streamline its assembly and installation of kitchen frames. Vätternkök AB is a newly established company based in Jönköping, delivering kitchens, wardrobes, and bathroom furnishings in flat packs directly to construction sites. The kitchens are assembled and installed on-site by employees or hired carpenters.The project group conducted the thesis work over 18 weeks during the spring of 2024. Throughout the project, the group conducted literature reviews on how the assembly and installation of kitchen frames can be streamlined, performed analysis on both the construction and the carpenter's work onsite during a field study in Hultsfred, and developed proposals for improvements to the construction. What the group discovered during the field study was that the construction site was significantly behind schedule, making it difficult for the carpenter to carry out their work. This was the second installation the company conducted, and the same problem occurred as with the first installation.The group also conducted timing measurements to identify tasks that take up an unnecessarily long time and transitions between tasks. Through these timing measurements, the group identified several tasks that unnecessarily take a long time and could be changed or eliminated. The first is that the feet mounted on the kitchen frame require four holes each, which must be measured and drilled, where all kitchen frames have two or four legs. The second is the back panel of the kitchen frame, which is situated in a slot extending the height of the frame and then being stapled or nailed with a nail gun to keep it in place.With all the information from the literature study and analysis, the project group proposed changes to the existing construction. The first proposal is to pre-drill the holes for the feet of the frame, thus eliminating the steps of measuring and drilling the holes and saving time. The second proposal is to extend the bottom panel of the kitchen frame, blocking the slot when the back panel is attached and therefore eliminating the need to staple or nail it. Another proposal for the back panel is not to mill the slot all the way through the side panel and thus attach the back panel without stapling or nailing it. Additionally, the proposal regarding the feet can be combined with any of the proposals for the back panel, further streamlining the assembly and installation process.The conclusion of the work is that there is great potential for time savings during the assembly of the company's kitchen frames. By improving the construction, a saving of 26% of the assembly time for the frame can be achieved. The project group believes that further improvements can be found in the assembly method.The biggest time savings the company can make is by improving efficiency on-site. The assembly of kitchen frames ultimately became a very small part of the total time spent on-site. The messy construction site resulted in a lot of wasted time for the carpenter. By better planning to ensure that the assembly takes place at the right time, so it can be spent more efficiently.
